Notes
1. The volume can be used as a Cnt Ac-J pair volume for delta resync.
2. Cnt Ac-J pair must be created first, otherwise No.
3. For information on Auto LUN, contact HP Technical Support .
4. Cnt Ac-J pair status must be other than COPY or PAIR to use the P-VOL as a source volume and perform volume
migration. The migration operation stops if Cnt Ac-J pair status changes to COPY or PAIR.
5. The volume can be used as an S-VOL only when you restore a Cnt Ac-J pair or perform the horctakeover operation,
though even in these cases, it cannot be used in a pair for a delta resync operation
